HTTP Status Code Checker

dead simple binary to check http status code(s) returned from health-check endpoint.

Why not just use cURL?

cURL can definitively do the job as long as you are willing to mix the shell script to parse the payload. Specially if you want to cover a range of status instead of a single HTTP code.

The http_status_code_check command removes the necessity of parsing the HTTP status codes and let you dealing only with the program exit code itself:

• 0 - if the status code is inside the list of expected ones
• 1 - if the status code is outside the list of expected ones

Also. In a scenario where one of the containers get compromised a tool like curl can become a liability helping the intruder having an easier time fetching more external data/tools.

Install

cargo install http_status_code_check

or

curl -L https://github.com/rmoraes92/http_status_code_check/releases/download/0.1.2/http_status_code_check \
  > /bin/http_status_code_check && \
  chmod 755 /bin/http_status_code_check

Usage

• Checking for single code:

http_status_code_check -u http://google.com -s 200

• Checking for multiple codes:

http_status_code_check -u http://google.com -s 201,200

Example Mocking AWS ECS
